If you do get into multichannel Hi Rez music, due to the differing catalogs, you will appreciate the ability to play both DVD-A and SACD. I absolutely love them both but, though I can give no earthly reason why, I slightly prefer SACD.

My experience went the other way. For whatever reason, I've liked the DVD-A versions better than SACD. I have the last two Bjork albums in both formats, and DVD-A did more for me. However, I have a fairly cheap universal player, and aren't there very few players that actually process SACD's DSD correctly?
